Criminal Complaint Details Naperville Suspect's Movements

The Federal Aviation Administration will conduct a complete review of its procedures in the wake of Friday's act of sabotage inside a radar facility near Chicago, Administrator Michael Huerta said Monday.

Over the next 30 days, Huerta said a team of FAA employees and labor union representatives would be reviewing security practices and plans for dealing with unexpected incidents. He asked them to "think as creatively as possible."

The FAA has heightened security at all its air traffic facilities in response to the incident, but the review will look at what more can be done on background checks and access, Huerta said. "Everything needs to be on the table," he said.

Brian Howard, 36, of Naperville, entered the building around 5 a.m. Friday, and about 30 minutes later posted a suicide note on Facebook in which he apologized to loved ones for leaving "a big mess," according to a federal criminal complaint.

Minutes later, someone at the facility called 911 to report the fire. A relative who saw the Facebook post also alerted authorities. Paramedics followed a trail of blood past a gas can, two knives and a lighter and found the suspect slashing his throat, the complaint said. He also had cuts to his arms.

One of the paramedics pulled the knife from his hands as the suspect called out, "Leave me alone," according to the complaint.

Howard worked at the facility for eight years and was involved with the facility's communications systems. He was recently told he was being transferred to Hawaii.
